Jaguars head coach Doug Pederson called Friday a “big day” for determining running back Tank Bigsby’s availability for Jacksonville’s Week 11 road matchup with the Detroit Lions.

Bigsby did not practice Wednesday or Thursday while nursing an ankle injury, which he suffered in Week 7 against the New England Patriots and aggravated Sunday against the Minnesota Vikings.

“Tank’s gonna go today,” Pederson said Friday. “We’ll see. Optimistic, you know. But obviously, today will be a big day for him.”

Bigsby has rushed for 519 yards and four touchdowns over 95 attempts this season and added three receptions for 36 yards.

Pederson revealed that Jacksonville’s starting left guard, Ezra Cleveland, will likely play against Detroit after missing the Jaguars’ last two games with an ankle injury suffered in Week 8 against the Green Bay Packers.

“Ezra should be good to go,” Pederson said.

Jacksonville vs. Detroit will kick off at 1 p.m. ET on Sunday, at Ford Field.
