VIrginia Tech LB commit Alan Tisdale

Former four-star linebacker Alan Tisdale will miss his true freshman season at Virginia Tech, according to Defensive Coordinator Bud Foster.

Foster announced on Tuesday that Tisdale will undergo surgery for an undisclosed injury and will be “put on the shelf” for the upcoming season.

The No. 23 outside linebacker in the 2018 recruiting cycle, Tisdale committed to Virginia Tech over offers from Louisville, Maryland, Mississippi State, NC State, North Carolina, Notre Dame, Ole Miss and others.

Tisdale enrolled at Virginia Tech during the winter and took part in the Hokies spring workouts.

According to Justin Fuente, Tisdale had a “good spring” after enrolling in Blacksburg.

Over the summer, Tisdale added four pounds to his 6-foot 3-inch frame, checking into fall camp at 214-pounds.

With Tisdale no longer in the running to replace first-rounder Tremaine Edmunds, Foster said that sophomore Dylan Rivers and freshman Dax Hollifield are the two main competitors for the starting spot, adding that he believes both will play in 2018.

Both Rivers and Hollifield were 247Sports Composite four-star recruits.
