Sturgis will miss the rest of the team's OTA sessions with the injury, reports the Miami Herald. Sturgis was 29-of-37 on field goals last season, and just 9-of-16 from beyond 40 yards.
Bogotay was a tryout player at rookie minicamp and previously a member of the Browns' practice squad. Gottschalk was with the Chiefs' practice squad last season.
"Am I thrilled about it? No, I don't think any other kicker is," Prater said in an interview with ESPN.com. "You know, they make these rules and they never talk to any of us about it. I don't know. I just feel that eventually they are just trying to weed kicking out of the game completely. It's something we'll have to deal with and hopefully make them all."
He also questioned the motive from the league with making this kind of rule change.
"I don't know what the owners and (NFL commissioner Roger) Goodell and all them are thinking," Prater said. "But I'm just going to try and do my job and keep my mouth shut for the most part."
OTA practices are voluntary and players are not required to attend.
Linebacker NaVorro Bowman was also not present though he was given the day off by 49ers coach Jim Tomsula. Bowman missed the 2014 season after sustaining an ACL tear during the 2013 playoffs.
Walsh said there's been "a little bit of communication" about a new deal.
"I would love to stay a Viking," he said. "This is the team that drafted me and put that faith in me to be an NFL kicker. But at the same time, I’ve had a Pro Bowl year here, I’ve had success and there’s been a lot of long attempts that we’ve made, so the numbers are going to have to be right for both of us. But when it comes down to it, I hope I can stay with the Vikings."
NFL owners approved the competition committee's proposal to move the placement of the football on the extra point attempts form the two to the 15-yard line, making what used to be a 20-yard kick into a 33-yard attempt. Brown sees the change as an opportunity to showcase the skills of a kicker.
“I’m excited about it,” Brown, the Giants’ kicker, said today. “I believe it adds higher value to a person that come out in December in bad weather and still be consistent. Those qualities are still very exciting to me. It’s a play that you won’t turn the TV off for anymore. Every point matters in this game and now with the longer extra point, there’s added difficulty to it. It’s not a gimme. There are levels of excitement that are going to make the game more appealing when scores are very, very tight.”
Brown was perfect last season during extra point attempts, going 44 for 44.
Graham is a 14-year veteran of the NFL. He appeared in all 16 games for New Orleans in 2014, going 19 of 22 on field goals and 46 of 47 on extra points.
