Report: Marshawn Lynch has hamstring injury, is '50-50' for Monday's game

SEATTLE -- All is not physically well in the world of Beast Mode.

Seahawks star running back Marshawn Lynch sat out most of the second half in Sunday's 26-0 win over the Chicago Bears with a hamstring injury.

Now, according to NFL insider Adam Schefter, Lynch's status for Monday's MNF game against the Detroit Lions is uncertain.

According to the Oregonian, an MRI done on Lynch's hamstring showed no serious damage. However, it is just one of several nagging injuries that has plagued the running back early this season. Lynch previously battled calf problems and a lower back issue.

Running back Thomas Rawls, Lynch's back-up, will look to build on his big game against the Bears. Rawls rushed for a career high 104 yards on 16 carries, averaging 6.5 yards per carry on Sunday.

The Seahawks (1-2) hope to break even this week against the struggling Lions (0-3).
