Cliff Avril's neck injury may be career-ending

According to coach Pete Carroll, the veteran is "seriously looking at a big decision" regarding his playing career and future in the NFL.

Cliff Avri's neck injury is more serious than initially thought and could jeopardize the career of the Seahawks defensive end.

Fox Sports reporter Jay Glazer said during the Fox NFL Sunday pregame show that Avril's injury, suffered during last Sunday's 46-18 win over the Colts, might be a career-ender.

The 10-year veteran has played sparingly this season, with just two tackles and a sack. He was inadvertently kicked in his chin against the Colts and has been experiencing numbness in his arms this week as the Seahawks prepared to play the Rams Sunday.

Seahawks coach Pete Carroll said earlier this week the team is in a "holding pattern" when it comes to Avril's future. Glazer said Avril is now mulling whether or not he wants to continue his playing career.

Avril, 31, has spent the last five seasons with the Seahawks after beginning his career with the Lions. He has 74 career sacks and had a dominant performance in Super Bowl XLVIII with three tackles and a safety. Avril also provided the pressure on then-Broncos quarterback Peyton Manning that resulted in a fluttering pass that was intercepted by linebacker Malcolm Smith and returned for a touchdown in Seattle's 43-8 victory.
