There are no plans for left tackle Trent Williams to reunite with the 49ers for the first time since the Super Bowl unless they agree to adjust his contract, according to multiple reports. Williams remains a holdout 14 days before San Francisco is scheduled to host the New York Jets on "Monday Night Football" to wrap Week 1 of the regular season. At issue is the lack of guaranteed money remaining on Williams' contract.

He was placed on the Did Not Report list by the 49ers on July 25 but the team is facing a roster decision before 4 p.m. ET on Tuesday, when all 32 NFL teams are required to reduce their 90-man training camp rosters to 53.

Williams, an 11-time Pro Bowl selection, is owed $74.76 million over the next three seasons. None of that sum is guaranteed.

Williams cleared the midway point of six-year, $138.06 million deal and is entering the fourth year of the agreement. "It's something I knew could be a possibility, and I was hoping that he would be here," 49ers coach Kyle Shanahan said of Williams last month.

"But I knew it could be a possibility, and I feel pretty confident that it will all work out in the long run and he'll be here, and we'll get on the same page with everything. It's just one day of practice, and I think Trent will be all right missing a few practices." Shanahan said last week he hoped a deal with Williams was getting close.

Williams was a first-team All-Pro in each of the past three seasons. The 36-year-old is entering his fifth season with San Fran.
