Kansas City Chiefs wide receiver Jason Avant makes a catch.

The number of players injured reached a training-camp high 13 players Tuesday morning.

The number remained at double-digits for the fifth practice in a row, but a trio of players had the day end early in the next-to-last practice this week.

Albert Wilson was on the field during the early-morning stretching session but left with an illness. Later in practice, defensive end Mike Catapano and offensive guard Marcus Reed left with a groin injury and ankle injury, respectively.

The rest of the injuries were the same as the previous reports: Jeremy Maclin (neck), Dee Ford (concussion symptoms), Nick Williams (concussion), Garrett Frye (knee), Jeret Smith (hamstring), Tyler Bray (knee), Demetrius Harris (foot), Junior Hemingway (hip), Dontari Poe (back) and James-Michael Johnson (calf).

• With Maclin and Wilson both out for the day, the first-team wide receiver reps went to Frankie Hammond Jr. and Fred Williams — both second-year pros.

Hammond caught the first two passes from Alex Smith when the Chiefs went into 11-on-11 drills.

• Smith connected on a long passing play to Tello Luckett against rookie Steve Nelson, while veteran Jason Avant made a one-handed catch near his hip during drills.

• Perhaps the biggest take away from the 11-on-11 was the play of linebacker Frank Zombo, who twice beat left tackle Donald Stephenson around the end for what would've been sacks in a game setting.

• The third-team offense yielded what would've been two sacks as well.

Cornerback Deji Olatoye had a similar play with Aaron Murray at quarterback but with sacks not counting, Murray stepped up in the pocket and hit L'Damian Washington in stride down the sideline.

Defensive end Vaughn Martin also got to Murray after beating the right tackle, but Murray completed a pass to fullback Spencer Ware under pressure.

Later in the day, Martin picked up a bad snap and started running toward the end zone before whistles blew the play dead.
