University of North Carolina center Lowell Dyer strained a muscle in his right shoulder during practice last week and did not play in Saturday's win at Connecticut.
Dyer, a fifth-year senior from Durham, N.C., will be out 3-4 weeks while undergoing rehabilitation.
His status will be updated after that time. Dyer came to Carolina as a walk-on and earned a scholarship prior to the start of the 2008 season.
A 2009 candidate for the Rimington Award, which is given annually to the nation's top center, Dyer has started 16 games in his career.
Tight end Zack Pianalto dislocated the subtalar joint in his right foot during Saturday's game at Connecticut.
The dislocation was reduced on the field by team physician Dr. Jeffrey Spang.
Pianalto will be out 3-4 weeks while undergoing rehabilitation. His status will be updated after that time.
A junior from Springdale, Ark., Pianalto had career highs in receptions (7) and receiving yards (87) vs. the Huskies, and scored the game-tying touchdown with 2:36 remaining.
North Carolina's weekly injury report will be available Thursday after practice.
