Dick the Bruiser. He was reinstated, along with Hornung, on March 16, 1964, by NFL commissioner Pete Rozelle. Upon returning to action in 1964, Karras once refused when an official asked him to call the pregame coin toss. "I'm sorry, sir," Karras replied. "I'm not permitted to gamble." During his first year back, player discontent with head coach George Wilson resulted in Karras asking to be traded. However, the Lions settled the issue when they fired Wilson after the season. From 1960 to 1966, except for his suspension in 1963, he played next to Roger Brown, forming a formidable pair of defensive tackles, until Brown was traded to the Los Angeles Rams. After another season of controversy under new head coach Harry Gilmer, Karras was rumored to be ready to play out his option and sign with the expansion Miami Dolphins of the American Football League under his former coach Wilson. Instead, Karras signed a seven-year contract with the Lions on May 20, 1966, with Wilson stating that Karras had used the threat of signing with Miami to garner a large deal with Detroit. Despite the new contract, controversy remained, as Karras and Gilmer sparred in midseason, with the coach reportedly ready to release the veteran defensive tackle. As before, it would be the coach who would depart, with Karras's former teammate Joe Schmidt taking over for Gilmer. On June 4, 1967, Karras once again hinted he would retire to work at a new business venture; once training camp began, though, Karras was back with the Lions. During that preseason, he jokingly commented that he would walk back from Denver if the AFL Broncos defeated the Lions. When it actually happened, Karras backtracked and flew home on the team plane. He was still an All-Pro selection from 1967 to 1969. Despite not allowing a touchdown in the divisional round of the 1970 NFL playoffs, the Lions lost to the Dallas Cowboys his first playoff game and his final game. After the 1971 preseason, while rehabilitating a knee injury suffered the previous year, Karras was released, ending his playing career at age 35. From 1958 to 1970, the Lions were over .500 six of the 13 years, making the playoffs only once, in 1970, with a record in Karras's final year. Aside from 1970, their best years were 1962 and 1969 In 1962, the Lion defense allowed 177 points (12.6 points/game),
