Boss in Oakland for a workout

Eli Manning said he has called Kevin Boss and hopes Boss will be with the Giants on Thursday.

We assume Manning was being optimistic.

On Wednesday, Boss worked out for the Oakland Raiders, who are scrambling to replace Zach Miller.

Boss caught passes from quarterback Jordan La Secla for about 15 minutes and then visited the Raiders locker room at their facility in Napa.

“We're going to work him out, see where he's at," Raiders head coach Hue Jackson said according to CSN California. "He’s a big target. He’s a big guy... he can run, and he’s played in tough games before."

Boss looked impressive according to Comcast SportsNet California Raiders’ beat writer Paul Gutierrez.

"It all comes down to the coaches' decision and if they feel like he fits our offense," Raiders quarterback Jason Campbell said about Boss, per Gutierrez.

The Raiders lost Miller when he signed a five-year, $34 million deal with $17 million guaranteed.

The Giants are trying to re-sign wide receiver Steve Smith and Boss, two major pieces in their offense. Manning is extremely comfortable with both in the passing game. Losing one or both will be a critical loss for the Giants.

With Smith still recovering from microfracture surgery, the Giants can use Boss over the middle as a big target. Perhaps it is a coincidence or perhaps not that the Giants threw quite a bit in practice to tight ends Travis Beckum and Jake Ballard. TE Ben Patrick, who was signed this week, can't start practicing until Thursday at the earliest.

“I’ve talked to both of them,” Manning said today of Smith and Boss. “They are just trying to figure things out. Obviously Kevin –- a little bit more urgency to that one just because he can come back and start practicing right away, as soon as we sign him, hopefully starting tomorrow and getting a tight end.”

“Steve still has some more rehab to do and wouldn’t be able to come in and probably, because of the injury, practice right now,” Manning said. “Hopefully those things get worked out soon and we can get them back here.”
