The severity of Womack’s condition was not known, but he likely sustained the injury during practice on Wednesday.
Womack’s status for the 49ers' Week 2 matchup with the Los Angeles Rams on Sunday at SoFi Stadium appears to be the only concern for the 49ers.

Nacua was a fifth-round draft pick from BYU. He got his career off to an impressive start in the Rams’ 30-13 victory over the Seattle Seahawks on Sunday.
Quarterback Matthew Stafford targeted Nacua 15 times, and the pair connected on 10 catches for 119 yards.
