The San Francisco 49ers have been cautious with the return of defensive back Jimmie Ward, who has been on the physically-unable-to-perform (PUP) list since the start of training camp due to a hamstring injury. The 49ers put him through a workout last week but ultimately decided against bringing him back in time for the team's second preseason game, which ended up being a 33-14 loss to the Denver Broncos.

Head coach Kyle Shanahan said on Sunday that the 49ers plan to put Ward through a lengthy workout on Monday and another on Tuesday. The hope is that he can be activated off of the PUP list and be made available on Wednesday. Monday and Tuesday are days off for 49ers players.

"Yeah, we're going to put him through again," Shanahan said. "We put him through a hard workout last week. Tomorrow we're going to have our DB coach Jeff Hafley go out there and really take him through a hard workout that's more pertained to exactly football. So, we're going to see how he responds to that on Monday and Tuesday and hopefully, we'll get him ready to go by Wednesday."

Ward is entering his fourth season with the 49ers and has accumulated 110 tackles, two sacks, 20 passes defensed, and two interceptions over the past three seasons. The new coaching staff was impressed enough with Ward that the team picked up his fifth-year option earlier in the offseason, which will keep him under contract through the 2018 season.

Ward ended the 2016 season on injured reserve following a shoulder injury suffered during a December matchup against the Atlanta Falcons.
