KJR 950's Ian Furness on Costa Injury

Ian spoke with Jay Allen, Sports Director at Portland's KXL 95.5 "The Game" - the Ducks' flagship station.

Allen said Costa "tweaked" his knee during a closed practice at Autzen Stadium. It is unknown if it is the same knee in which he suffered an ACL tear last year. Allen said his sources are calling the injury "serious", which seems to be the catch word of the day.

Today's practice was scheduled to be open, but was closed after the Costa injury.

Costa, the Redshirt Sophomore didn't play last year after blowing out his knee in practice. Costa played a little as a frosh, and then redshirted after the injury.

Costa, 6'1" 215, is a mobile quarterback who relies on his legs to run the Chip Kelly spread.

If Costa goes down, the Ducks will likely turn to Justin Roper, who was impressive in the Duck's Sun Bowl win last year, going 17-30 for 180 yards and four TD's in the 56-21 win over South Florida.

True frosh Chris Harper, a true dual threat QB, has also been pressing for playing time.

"Harper was highly recruited out of Wichita, Kan. He's very athletic, but also very green," Allen said.

"If Costa is out, Roper is your starter, but we will be seeing Harper a lot sooner than later," Allen said.
