On Monday, fullback Larry Centers agreed to a contract extension and slightly reduced salary for 2002, the Rochester Democrat and Chronicle reported.
On Tuesday, Riemersma and his agent, Jack Wirth, said they hoped to have the tight end's contract restructured as soon as Thursday.
They are working against a virtual deadline of June 1, when the Bills could release Riemersma to save salary-cap money. He is scheduled to make $2.525 million this year, and $3.5 million in 2003, the final year on his contract. This year's salary is one of the highest for any NFL tight end.
"We don't have anything scheduled," Wirth said of his negotiations with the team. When asked whether he had made a proposal to the team, the agent said from his Chicago office, "We have gone through all that.
"Nothing has taken place yet. We would hope it will soon. We would like to get this done while this mini-camp is on."
"I think it has to be soon," said Riemersma. "Obviously, it has to go one way or the other, and I want to be here. The main point I want to get across is that it's not true that Jay refused to restructure his contract and help out the team. I was never dead set against it."
He didn't help his position Tuesday by limping off the practice field with what head coach Gregg Williams called a "tweaked" left hamstring.
Williams added, "At this time of year, he can watch the rest of the mini-camp. We know what he can do."
Riemersma, who turned 29 last week, posted career highs of 53 catches and 590 yards last season. He ranks second among Bills tight ends, behind Pete Metzelaars, with 172 career receptions for 1,954 yards and 20 touchdowns. Riemersma is three behind O.J. Simpson for 10th place on the team's overall all-time receptions list.
New quarterback Drew Bledsoe said he was excited about working with both Riemersma and unrestricted free agent Dave Moore, who have both been in the lineup at some times during the mini-camp. "Jay is a guy I have admired for a long time from the other side of the ball," said the former Patriots QB. "For my first seven years, I had Ben Coates, and watching Jay from afar, I think he's a guy who can fill that role."
Bills president Tom Donahoe would say only that he had had discussions with Wirth concerning Riemersma.
The 33-year-old Centers, entering his 13th NFL season, signed a two-year contract with Buffalo before last season. It is believed the new agreement would extend his contract through 2003 and provide additional bonus money this season.
