The San Francisco 49ers open their 2018 OTAs later this morning, marking the start of phase three of the offseason workout program. The team will conduct OTAs May 21-22, May 24, May 29-30, June 1, June 4-5, and June 7. That will be followed by their three-day mandatory minicamp June 12th to 14th.
The start of phase three marks a change in what the players and team can do on the field. Players can wear helmets during drills for the first time, and we’ll get to see team offense vs. team defense drills. In the previous phase, the offense could do drills and the defense could do drills, but they could not do them against each other.
