FRISCO – The sometimes challenging game of figuring out which players will be inactive for a team going into a game, in the case of the Dallas Cowboys, just got substantially less challenging.

The Cowboys have ruled out six players for Sunday night’s game against the Philadelphia Eagles. They are: Wide receiver Tavon Austin (groin), defensive end Taco Charlton (shoulder), defensive tackle David Irving (ankle), linebacker Sean Lee (hamstring), left guard Connor Williams (knee) and linebacker Joe Thomas (foot).

Cowboys owner Jerry Jones on Friday morning appeared on 105.3 The Fan and mentioned of 3-5 Dallas, “I think we are going to be good with our health. That’s good in general.”

Except for the fact that he comes by it naturally, I’m not sure where Jerry is getting his optimism from.

In Austin’s case, I’m told his groin is so problematic that the team considered moving him to the injured reserve list before instead opting to cut another veteran wide receiver, Deonte Thompson, a move fueled by the Cowboys’ desire to elevate receiver Noah Brown from the injured reserve list to the active roster. Dallas did the same with receiver Lance Lenoir, bringing him up from from the practice squad.

In Lee’s case, the Cowboys believe he might miss a month of time, and at some point, the injured reserve list may become an option for him.

So the roster is full to 53, with the 46-man roster for the Eagles game needing to be set. And it pretty much is: Austin, Charlton, Irving, Lee, Williams (knee) and Thomas all being out leaves only one more spot, sure to be filled by third QB Mike White. The good news — and this may be what Jerry has on top of his mind when he was reflecting on the issues of the day here at The Star — is that tight end Geoff Swaim and defensive end Randy Gregory seem set to return to action against the 4-4 Eagles.

Both players enter the weekend listed as questionable, but as Cowboys247 reported earlier this week, both actually practiced to some degree on Wednesday (a fact that was in conflict with the team’s official report on the day). Dallas tried to use its other three tight ends in Monday night’s disappointing home loss to the Titans, but would welcome back the starter at the position assuming Swaim is recovered well enough from a knee sprain.

In Gregory’s case, I’m told he spent most of the week working as the backup right defensive end. DeMarcus Lawrence is the starter there, of course. Tyrone Crawford is scheduled to start at the other end, kicking outside due to the healthy availability and hopeful contributions of tackles Antwaun Woods and Maliek Collins.

The biggest injury issue for Dallas might be the struggle to replace Williams in an already struggling O-line. Adam Redmond began the week as the leading candidate to start at left guard, but Xavier Su’a Fila came on later in the week, and now the journeyman is expected to be with the first team.
