What happened: Los Angeles Chargers cornerback Tarheeb Still has officially changed his jersey number from No. 29 to No. 4. Still debuted the new look during the team's OTA sessions this week as the Chargers continue their offseason program under head coach Jim Harbaugh.

Why it matters: The move carries significant franchise weight as No. 4 was famously worn by Harbaugh during his playing days as the Chargers' quarterback in 1999 and 2000. Still is among the first defensive players to utilize the NFL's expanded jersey number flexibility for a single-digit assignment.

What to watch: The Chargers will continue their offseason program with additional OTA sessions scheduled through mid-June before transitioning to mandatory minicamp.
