As soon as I published that Lions rookie running back Mikel Leshoure had been carted off the field with an apparent lower left leg injury, Detroit News beat writer Chris McCosky tweeted that Leshoure is out for the season with a torn achilles. 97.1 The Ticket tweeted that Jim Schwartz confirmed the injury. According to SB Nation Detroit's medical experts, the injury was likely known as soon as Leshoure was tended to by team doctors on the field via the Thompson Squeeze test.
This isn't a completely devastating blow to the Lions offense, but Leshoure was having a great rookie camp en route to complementing the skilled Jahvid Best this year.
The Lions will almost certainly look to pick up another running back now that Leshoure is out for the season, so look for names like Ricky Williams, Laurence Maroney, or even former Lion Kevin Smith to pop up as potential replacements on the team's radar.
