ESPN Twin Cities reports Percy Harvin and coach Leslie Frazier had yet another heated exchange that likely contributed to the receiver being placed on injured reserve earlier this month.

It's the third documented issue with Harvin and the organization since June. The exchange is believed to have begun in the training room and has fueled speculation that the "deteriorating" relationship between the two men could lead to Harvin's exit from Minnesota. Seeking a new contract and frustrated with the identity of the Vikings offense, Harvin briefly issued a trade request last offseason. The team will have to decide whether to offer him a long-term deal heavy on performance-based incentives and escalators or prepare to shop him in March and April. One NFL personnel man estimates that Harvin would draw a second- or third-round pick in a contract year.
