Coach Charlie Strong confirmed the move via Twitter on Thursday morning, saying, "I'm excited to have Tyler Gabbert officially join our football program."
Gabbert announced his plans to transfer from Mizzou in May. He would have gone into fall camp in a competition with James Franklin to replace his brother, Blaine, as the starter there.
Instead, he will sit out the 2011 season because of NCAA transfer rules. Louisville spokesman Rocco Gasparro said Gabbert will have three years of eligibility remaining.
His choice certainly is an interesting one, considering hopes are high for true freshman Teddy Bridgewater to take the reins at quarterback this season for the Cardinals. Bridgewater and junior Will Stein both are expected to get playing time.
Gabbert does have a connection to Louisville. Quarterbacks coach Shawn Watson recruited both Gabbert brothers when he was offensive coordinator at Nebraska. Blaine and Tyler both had given verbal commitments to the Huskers before signing with Missouri.
The younger Gabbert has yet to play in a collegiate game. Blaine Gabbert left school after his junior year and was taken No. 10 overall by the Jaguars in April's NFL draft.
