Injuries at the safety position have the Detroit Lions looking for help for their secondary just a few days before the start of training camp.

The Lions worked out former Indianapolis Colts safety Stefan McClure on Thursday.

McClure had an injury-filled career at Cal and spent part of last season on the Colts' practice squad but was waived by the team in May.

The Lions have seven safeties on their 90-man roster, but two – Don Carey and Rolan Milligan – are on the physically unable to perform list.

Carey, a longtime special-teams standout for the Lions, sat out spring practice with a knee injury, and Milligan is dealing with an unknown ailment.

The Lions return starting safeties Glover Quin and Tavon Wilson, and Miles Killebrew is expected to play a bigger role in his second NFL season. Cornerback Alex Carter also converted to safety earlier this year, but the potential fifth safety spot – behind Carey – is up for grabs this preseason.

The Lions open training camp on Sunday.
