 Arkansas running back Juan Day will miss the remainder of spring practice after suffering an anterior cruciate ligament injury.

Day, a redshirt freshman, suffered the injury in practice two weeks ago, Arkansas coach Bret Bielema said on Twitter. Bielema said Day had surgery on the knee Monday.

It is the second ACL injury Day has suffered in less than two years. He tore the ACL in his opposite knee in 2013, forcing him to miss most of his senior season at North Little Rock High School.

It's unclear whether Day will be cleared to play any during the 2015 season. ACL recoveries typically last around six to nine months.

Day was the most likely candidate to be the Razorbacks' third-string running back behind returning 1,000-yard rushers Jonathan Williams and Alex Collins.
