With help from SID Tim Tessalone, I’ve been able to extrapolate that USC’s first spring football practice on March 28 will begin at 10 a.m. The start time previously had been listed as TBD.

USC is playing host to a football clinic that weekend, and, according to the schedule, attendees can observe practice at 10 a.m. that Saturday.

Practice is open to the public as well. Here’s the tentative spring schedule, in case you missed it previously:

• March 28, Saturday, 10 a.m.
• March 31, Tuesday, 4 p.m.
• April 2, Thursday, 4 p.m.
• April 3, Friday, 4 p.m.
