Lions work out cornerback Terrell Thomas

After wrapping up their OTA practice on Wednesday, the Detroit Lions turned their attention to a workout involving free-agent cornerback Terrell Thomas, according to Josh Katzenstein. Thomas, who worked out for the New England Patriots last week and visited the Oakland Raiders and Carolina Panthers back in March, is looking for a new team after being a member of the New York Giants from 2008-13.

Although Thomas entered the NFL in 2008, he's only actually played in four seasons. That's because he suffered a torn ACL before the 2011 season, and just as he was working his way back a year later, he tore his ACL again. He also tore his ACL in college, meaning he's suffered that injury three different times. (Ryan Broyles has some company when it comes to bad injury luck.)

Thomas did finally make it back from his ACL injuries in 2013. He started seven games for the Giants and played a full season, and he finished the year with 67 tackles, 1.0 sack, 7 passes defended, 1 interception and 1 forced fumble. Pro Football Focus gave him a +0.4 grade for the 2013 season, which put him 52nd in the league. (Interestingly, that's the same grade that the Green Bay Packers' Sam Shields received, and he got a four-year deal worth $39 million this offseason.)

So why did the Lions take a look at Thomas? They may have more than enough bodies at cornerback right now, but perhaps Thomas could be an option if Chris Houston opens training camp on the PUP list. Houston just had toe surgery a couple weeks ago, and it's unclear at this point when exactly he will be back. If the Lions aren't confident about his status going forward, they could decide to bring in Thomas in order to have another starting-caliber cornerback on the roster.
