Liles (concussion) is out indefinitely after sustaining a concussion in Sunday's game against the Lightning.

EDGE Analysis

Liles concussion occurred when he crashed into the end boards during Sunday's tilt. The blueliner did not travel with the team for Tuesday's game, presumably to receive treatment. It's unclear at this point how long the 36-year-old will be sidelined. With Zdeno Chara ailing as well, the Bruins will likely look to Kevan Miller and Brandon Carlo to assume more playing time.

Liles (upper body) was not on the ice for the Bruins' morning skate in advance of Tuesday's game against the Flyers.

EDGE Analysis

Per the Boston Herald, Liles -- who left Sunday's game against the Lightning after crashing into the end boards -- did not travel with the team to Philadelphia for Tuesday's game. With both Liles and Zdeno Chara ailing, Joe Morrow and Colin Miller are on track to be part of the team's blue line corps Tuesday night.

The Bruins did not provide an update Monday on the status of Liles (upper body), who left Sunday's game against the Lightning after crashing into the boards.

EDGE Analysis

Liles is thus iffy for Tuesday's game against the Flyers, and with Zdeno Chara also ailing, the Bruins may be forced to call up up a blueliner from AHL Providence in short order.

Liles (upper body) left Sunday's game in the first period.

EDGE Analysis

The veteran defenseman hasn't done much this season, averaging 16:55 minutes per game with five points in 21 games. The severity of his injury is enough to pull him from the game, but it's currently unclear what it means for Boston's upcoming games.

Liles collected an assist on Boston's only goal during Friday's loss to Calgary.

EDGE Analysis

Entering Friday's contest, Liles was averaging just 16:46 of ice time per night, and the assist was only his fifth point of the season. The 35-year-old defenseman doesn't move the fantasy needle enough for ownership in any seasonal leagues.

Liles saw 22:13 worth of ice time in Thursday's 6-3 win over Columbus.

EDGE Analysis

Liles also saw 1:07 worth of power play time in the game, though at this stage of his career, the 35-year-old blueliner -- who recorded 21 points in 81 games last season -- is less of a threat on offense than he was earlier in his career. That said, Liles provides the B's blue line with valuable experience, mobility and prowess in the transition game.

Liles signed a two-year, $2 million contract with the Bruins on Friday, Sportsnet reports.

EDGE Analysis

Liles finished up the 2015-16 season in Boston after being traded in February from Carolina. The 35-year-old figures to keep providing depth on the blue line after averaging 19:19 of ice time over 17 appearances for the Bruins.

Liles completed the 2015-16 season with six goals and 21 points over 81 games between stints with Carolina and Boston.

EDGE Analysis

The 35-year-old blueliner is thus set to become a free agent this offseason, though Liles suggested Monday that he'd be open to a return to Boston. For the right price, Liles' experience and mobility could certainly be assets to the Bruins' back line in 2016-17.

Liles recorded two assists in 26:12 worth of ice time in Friday's 6-5 win over the Blues.

EDGE Analysis

After missing two games with a lower body injury, Liles was a welcome addition to the B's back line, with fellow blueliner Dennis Seidenberg sidelined, and Kevan Miller subsequently exiting Friday's contest with an injury. In 13 games in a Boston uniform to date, Liles has recorded four assists and a minus-3 rating, not eye-popping numbers, but down the stretch run, his mobility and ability in the transition game will nonetheless be assets to the Bruins.

Liles (lower body) will draw in to Friday's lineup against the Blues.

EDGE Analysis

Considered a game-time call entering the night, he should be deployed normally after missing two games due to the issue. While the 35-year-old isn't among the elite offensive blueliners, he does own two points in 12 games since joining the Bruins and can be a sneaky daily option as a member of the team's man advantage. However, he hasn't tallied a point in any of the last eight games, and faces a tough matchup again Friday against one of the league's hottest netminders in Brian Elliott.
