JMU head coach Mickey Matthews says junior starting running back Jamal Sullivan has a bad bruise on his knee.
Sullivan took a nasty hit in the third quarter in JMU's win over Liberty Saturday night. He did not return after rushing for a career-high 93 yards on 15 carries.
Matthews said Sunday that Sullivan's status for the Dukes' upcoming game against Hofstra is unknown.
"I don't know if he will play this week, but the doctors do not feel that there is any structural damage to the knee," says Matthews.
If Sullivan can't go, the Dukes will look to sophomores Scott Noble and Corwin Acker.
Acker took over most of the running duties after Sullivan left the game. Acker ran for two touchdowns in the second half, finishing with a career-high 147 yards.
The Dukes ended the contest with 301 yards rushing compared to 145 yards the week before against VMI, the lowest output for JMU since 2007.
"We thought going into the game that we thought we could run the ball on them early in the week, watching the tape, and I thought we made some strides in practice last week with our running game," says Matthews. "We felt confident we could run against them and we did."
