Prater was signed to a one-year deal after being cut by the Broncos on Oct. 3. He converted 21 of 26 field goals in 11 games for the Lions in 2014. Prater noted in January that he would like to return to Detroit in 2015, and now his wish has come to fruition.
It's the third time the team has used the franchise tag on a kicker, having previously tagged Adam Vinatier in 2002 and 2005. The designation puts Gostkowski in line to earn $4.126 million in 2015. He mae 35 of his 37 field goals in 2014, and his 94.6 percent rate was the best of his career.
With Gostkowski being tagged, Patriots safety Devin McCourty, who was a strong candidate to receive the tag, is set to reach free agency on March 10 if he doesn't re-sign with the team before free agency opens.
A franchise tag for a kicker would be an estimated $4.5 million, while tagging a cornerback would cost about $9.5 million. If no long-term deal can be reached and neither player is tagged, they'll become free agents March 10.
Tavecchio played with Oakland in the preseason last year before being cut. He was claimed by the Lions, but never played.
"I'm meeting with his agent tonight, in fact," Mayhew said. "Frank Bauer and I are going to sit down tonight and talk about Matt's situation and I'm looking forward to that dialogue."

Falcons GM Thomas Dimitroff spoke to the media at the Indianapolis scouting combine on Thursday and said the two sides are close. "Hopefully, that will come to fruition,” he said. “We are hoping that it gets finished expeditiously.”
Graham, who is entering his 15th season in the league, will earn $970,000 and Haralson, entering his 10th season, will earn $870,000.
Graham went 19 of 22 on field goals in 2014 with a long of 50 yards and also went 46 of 47 on extra points. Haralson totaled 35 tackles for the Saints in 2014 with three sacks.
Graham is in his second stint with the Saints. He was cut in the 2000 preseason without appearing in a regular-season game. He rejoined the team in December, 2013 and was the team's kicker all last season.
