Quincy

Butler

Bartell is set to undergo tests on Tuesday to help set a timetable for his return. He was replaced by Quincy Butler on Sunday.

Cruz got an injury settlement. Butler was seventh on the depth chart at corner at best. Terrell was fourth at QB. The others were undrafted.

Nickel back Justin King has been limited this week with a groin injury. Butler, claimed off waivers from the Cowboys last December, has mainly been a special teamer. Upgrade Matthew Stafford and Calvin Johnson this week, assuming they start.

Amendola, who was acting as the No. 3 receiver, took a big hit from Lions LB Zach Follett while returning kick. Newly acquired WR Brandon Gibson took over for Amendola in three-wide sets while CB Quincy Butler replaced him on punt returns. Amendola has the bye week to recover.

Butler also has a high ankle sprain on his left leg, making him a candidate for injured reserve.

His return is questionable. Butler has played far too much in a St. Louis defensive backfield this year that only has two mediocre-to-good players in Ron Bartell and O.J. Atogwe. Butler’s seen a lot of first-team snaps.

Cornerback Anthony Henry is struggling with a bruised thigh, so the Cowboys are looking for increased depth in the secondary.

Butler would struggle to make most teams’ rosters as more than a special teamer, but he was a major contributor for the lowly Rams on defense last year, recording 28 tackles and breaking up five passes. In camp, Butler will battle Kevin Dockery for nickel duties behind Ron Bartell and Bradley Fletcher.

Vobora finished 2009 as St. Louis’ starting SAM linebacker, playing well despite his unheralded status. Darby has proven no better than a No. 3 tailback in the pros. The club is high on Butler as a possible nickel back.

He has practice squad eligibility remaining.
