St. Louis Rams rookie defensive tackle Adam Carriker, the team's top pick in the 2007 draft, could miss all of the offseason training program after suffering a shoulder injury in Sunday's season finale.
Carriker, 23, will undergo surgery next week for a torn labrum. The injury, termed "significant" by coach Scott Linehan, will require about six months of rehabilitation.
The Rams are hopeful that Carriker will be fully rehabilitated for the start of training camp in July, but he probably will miss all of the minicamps and organized team activities in the spring.
A former Nebraska star, Carriker was chosen by the Rams as the 13th overall pick in the 2007 draft. He signed a five-year contract with a maximum value of $14 million and $9 million in gurantees.
Carriker appeared in all 16 games and recorded 30 tackles, two sacks and one pass defensed. He was named as the Rams' rookie of the year.
The shoulder injury occurred in the first half of Sunday's 48-19 loss to the Arizona Cardinals.
