LOS ANGELES -- Five days after being cleared to resume all physical activities, former UCLA linebacker Myles Jack was the main attraction at the school’s pro day Tuesday.

All 32 NFL teams sent representatives to the event, including multiple general managers, where Jack worked out publically for the first time since tearing his meniscus on the same UCLA practice field last September. Jack has not fully recovered from the injury -- he estimated he’s at around 80 percent -- and will hold another workout at UCLA on April 1, at which he’ll run a 40-yard dash. He chose not to run the 40 at the pro day, but did go through field drills and recorded a 40-inch vertical jump.

“It wasn’t where I wanted to be, but I definitely wanted to showcase there is nothing wrong with the knee,” Jack said. “I just have to get my conditioning up and get back into the flow and really get back into football shape.”

He said he hopes to run in the “low 4.6, 4.5” range on April 1, but doesn’t anticipate being 100 percent at that time.

There were 123 NFL personnel staffers in attendance -- scouts, coaches, GMs, etc. -- including San Francisco 49ers GM Trent Baalke, who holds the No. 7 overall pick. ESPN draft analysts Mel Kiper Jr. and Todd McShay both projected Jack to the Miami Dolphins with the No. 8 pick in their latest mock drafts.

UCLA coach Jim Mora said he noticed a hitch in Jack’s lateral movements, but wasn’t concerned about how the knee injury could affect Jack’s health long-term.

“When he’s at 100 percent he’s something special to watch,” Mora said. “He looked great today, just not 100 percent, but he’ll get there because he’s a hard worker.”

Jack will return to Tempe, Arizona, Wednesday, to resume his workouts at the Fischer Institute.
