With a little over four hours remaining in the NHL Trade Deadline, Bruins General Manager Peter Chiarelli will be looking to add some depth for the stretch run of the 2011-12 season.

But just like previous years, Chiarelli won’t be looking for a big, marquee name; i.e. Rick Nash

With a thin trade market, Chiarelli might have his hands full on trying to make a couple of deals. Outside of Nash — unquestionably the biggest name on the market — the selection is thin in terms of marquee players, but there are some out there that would immediately add depth, which is exactly what the Bruins need with the likes of Nathan Horton and Rich Peverley — and perhaps Johnny Boychuk — out due to injury.

Last year, Chiarelli added Chris Kelly, Rich Peverley, and even Tomas Kaberle to the roster before the deadline and the result obviously paid huge dividends. Similar type of acquisitions should also be expected this year in The Hub of Hockey.

Let’s take a look at some players that could don the Black and Gold by the end of the day.

Mike Knuble

Chiarelli has expressed interest in adding a forward who can play on the top three lines, and a depth defenseman who can log a good amount of minutes. The former would be exactly what they would be looking for in Washington Capitals forward Mike Knuble.

Although his stretch of eight straight 20-goal seasons will likely get snapped (just 3 goals in 57 games) the ex-Bruin could fill a role similar to Mark Recchi as a veteran and a mentor to some of the younger talent. This move would likely cost the Bruins very little — perhaps a mid-level prospect and/or a middle round draft pick — but even though Knuble’s current team is underachieving, the Caps still sit one point behind the Winnipeg Jets for the eighth and final playoff spot and three points behind the Southeast Division leading Florida Panthers.

Jaroslav Spacek

After being traded from the Habs to the Carolina Hurricanes earlier in the year — in exchange for Kaberle — the 38-year-old Czech defenseman is rumored to be on market and Boston is rumored to be a potential destination. This would undoubtedly be viewed as a short-term fix for the Bruins due to Spacek’s age and his status as an unrestricted free agent at the end of the season, but could be necessary at the right price, similar to Knuble.

Samuel Pahlsson

Like the two names mentioned above, Pahlsson would cost very little and could add some stability to the center position, especially with David Krejci moving to wing. His 11 points (2 G, 9 A) in 61 games isn’t anything to write home about, but neither were Chris Kelly’s when he arrived in Boston. And like Kelly, Pahlsson is known for his defensive presence up front, which is something that can be used on a third line.

Bryan Allen

Although the former fourth overall pick has underachieved during his tenure in the NHL, Allen is someone who can fit the Bruins’ mold with his physical presence. The 6-foot-5, 226 pound defenseman is averaging over 19 minutes of ice time and could be a solid replacement for Boychuk if he were to miss some time due to injury. At the right price, this would be a good addition.

David Jones, T.J. Galiardi and Daniel Winnik

Although the Colorado Avalanche sit two points behind the Dallas Stars for eighth in the West, the trio is rumored to be on the market. This would cost Chiarelli and company a little more to acquire one of the three forwards — like a Jared Knight or a Ryan Spooner for starters — with Jones (on pace for another 20-goal season) being the biggest name of the trio.

Ryan Malone

At age 32, it’s hard to imagine things getting better for Malone at Tampa Bay, especially since he is on pace for just 17 goals and a minus-21, which is far from his norm during his days in Pittsburgh. A destination change could be just what the doctor ordered for Malone to help resurrect his career, but any team looking to acquire him will have to carry his $4.5 million cap hit for the next three seasons.

Michael Ryder

Oddly enough, this former Bruin has been rumored to be on the market just months after signing a two-year deal with the Stars. With 25 goals this season, Ryder is on pace to break his career high set in the 2005-06 and 2006-07 seasons with the Montreal Canadiens and would unquestionably give the Bruins extra depth on the top three lines. But the chances of a Ryder reunion in Boston, at least for this season, is very slim.

Sheldon Souray

A more realistic option shall Boston and Dallas discuss a trade is Souray, who averages over 20 minutes of night and can add some offense on the power play. Souray’s best days are behind him, but, he could still add that depth if Boychuk misses time at the right price of course.
