Iowa State starting quarterback Jacob Park has taken a personal leave from the team and his return is unknown, the Register has learned.

Park is still on the team, Iowa State officials confirmed to the Register, but will not play Saturday — and potentially beyond — as he deals with unspecified medical issues.

“Jacob is a great young man dealing with some personal medical concerns,” Iowa State coach Matt Campbell said in a statement first obtained by the Register on Friday. “We are committed to helping him cope, supporting him on all levels and helping him prepare to get back on the playing field with his teammates as soon as possible.”

It's unknown at the moment who will take over for Park as the starting QB.

Campbell was not certain of a timeline for Park’s return. In the release, he noted that he cannot discuss medical issues pertaining to his players.

“We are focused on helping Jacob in any way we can,” Campbell said. “I know how important the football team is to Jacob and how important Jacob is to the football team. But supporting one another in difficult times is where we need to be.”

Park, a redshirt junior, has thrown for 1,181 yards, nine touchdowns and five interceptions this season. He’s coming off his worst performance of the season when he completed just 24 of 48 passes for 246 yards and three interceptions in a loss to Texas.
