Dallas Cowboys left guard Montrae Holland is nursing a partially torn left biceps - an injury which may end his season.
Holland is expected to undergo further tests to detail the severity of the injury, ESPN Dallas reported, citing multiple sources.
Holland suffered the injury during Saturday's 20-7 loss to the NFC East rival Philadelphia Eagles.
Signed prior to the team's game against the St. Louis Rams on Oct. 23, Holland has started 10 contests for the Cowboys (8-7).
Should Holland be unable to play in Sunday's pivotal game against the New York Giants (8-7), Kevin Kowalski or Derrick Dockery would get the nod.
