The Raiders are pushing for Donald Penn to take a pay cut, according to Michael Gehlken of the Las Vegas Review-Journal. Specifics are unclear, but Gehlken gets the sense that the Raiders will ask Penn to convert most or all of his $3MM guarantee into bonuses or incentives. 
Last year, Penn stayed away from the club as he pressured them for a new deal. His tactics worked as Oakland gave him a two-year, $21MM extension to remove his lame duck status.
Penn more or less played up to the expectations of the new deal last year as he graded out as Pro Football Focus’ No. 23 ranked tackle in the NFL. Unfortunately, however, he suffered a Lisfranc fracture against the Cowboys in December and remains on the PUP list as a result.
Ostensibly, the Raiders still want to move forward with Penn. First-round pick Kolton Miller has impressed in camp this summer, but the ideal arrangement for Oakland is to have both players starting on the offensive line. For that to happen, the 35-year-old may be forced to rework his contract.
Raiders are a mess.
That probably explains why they are so popular in Mexico.
Nothing like a team signing a guy to an extension and then asking him to take a pay cut a year later.
The injury understandably concerns the Raiders but Penn is in the driver seat as decent LTs are scarcer than hens teeth right now.
