The Detroit Lions have announced their offensive coaching staff changes, confirming some earlier reports and breaking the news of other changes. Let's start with the new pieces of news.

First and foremost, the Lions have hired Curtis Modkins as their new running backs coach. Modkins comes to Detroit after spending the last three seasons as the Buffalo Bills' offensive coordinator and running backs coach. In Buffalo, he coached guys like Fred Jackson and C.J. Spiller, two running backs who have had a lot of success as of late.

The Lions also announced that they have filled their vacant offensive line coach job by promoting Jeremiah Washburn, who was the assistant offensive line coach. Washburn, who is the son of former Philadelphia Eagles and Tennessee Titans defensive line coach Jim Washburn, has been with the Lions since 2009.

In addition to those two moves, the Lions confirmed that they have hired Bobby Johnson to coach tight ends. The team also confirmed that Tim Lappano, the old tight ends coach, will now coach wide receivers (instead of running backs, which was originally reported). Finally, the team has confirmed that Danny Crossman is out as special teams coordinator.
