Queries abound

Moss practiced Wednesday and Thursday, but did not participate in drills yesterday. He is listed as questionable (back) for tomorrow’s game against the Falcons at Gillette Stadium.

Coach Bill Belichick did not shed any light on Moss’s status; the injury report was released after Belichick’s afternoon news conference.

Moss was among 10 players on the injury report, joining fellow receivers Wes Welker (knee) and Julian Edelman (ankle), also a new addition to the walking wounded, as questionable.

Welker, who played in the opener against the Bills, did not play last Sunday but returned to practice Thursday. Belichick said Welker will once again be a game-time decision. Edelman, a rookie who played quarterback at Kent State, replaced Welker and had eight receptions for 98 yards against the Jets. Edelman participated in a limited role in practice this week.

The Patriots have had only four receivers active for the first two games of the season. Receivers filled up almost one-third of the injury report, meaning Joey Galloway, 37, and in his first season with the Patriots, and special teams captain Sam Aiken are the only healthy wideouts.

With quarterback Tom Brady trying to find his rhythm, Galloway was a frequent option last Sunday because Moss was double-teamed. Galloway and Brady were not in synch. Galloway had five catches for 53 yards, but he was thrown to 12 times. In fact, Galloway and Edelman were targeted by Brady 28 times but they combined for only 13 receptions.

Aiken can play offense and did last season occasionally, but wide receiver depth is clearly a problem. Terrence Nunn is on the practice squad, but the Patriots would have to make a corresponding move to promote him to the 53-man roster.

Asked if the team felt limited the last couple of weeks having only four receivers active, director of player personnel Nick Caserio said, “No, we realize there are only so many players we can go to the game with on a week-to-week basis. So, we’ve gone with four; sometimes we’ve gone with five. We’ve gone to the game with four receivers and felt confident in Sam if he had to go into the game, he’d go in and play well. So we haven’t felt there has been any sort of limitations with the game.’’

Moss, who has tweaked his back from time to time, showed no evidence he was hurting in the season opener in which he had 12 receptions for 141 yards. He was held to four catches for 24 yards in the 16-9 loss to the Jets, a game in which the Patriots were held without an offensive touchdown for the first time since 2006. Welker opened the season with 12 receptions for 93 yards but hasn’t played since.

Perhaps indicative of their concern over the collective health/depth of their wide receiving corps, league sources said the Patriots worked out Courtney Taylor, who started four games last season for Seattle and in two seasons had 14 receptions for 136 yards, and Larry Beavers, a rookie from Wesley College in Delaware, who was cut by Carolina.

The Patriots secondary also could be lacking against the Falcons. Starting cornerback Shawn Springs (knee) and starting strong safety Brandon Meriweather (ankle) were listed as questionable, as were corners Terrence Wheatley (knee) and Darius Butler (thigh).

Rookie defensive lineman Myron Pryor (calf) came off the report after being limited in practice.

The Patriots listed one player as probable: Brady (shoulder).
