Missouri quarterback Brady Cook will start against Memphis on Saturday in St. Louis, a source told ESPN's Pete Thamel.
Cook was a full participant in practice on Friday, per a source, after being limited earlier in the week with a knee injury suffered in the Tigers' 30-27 win over Kansas State, in which he threw for 356 yards and two touchdowns.
He'd been deemed questionable on Wednesday after missing practice on Tuesday.
Cook spent most of last season playing through a shoulder injury that required offseason surgery, as he tore his labrum against Kansas State last season.
