Dallas owner Jerry Jones suggested Friday that the Cowboys could sit quarterback Tony Romo and other starters for a preseason game Sunday night in San Francisco over concerns with the troublesome turf at Levi's Stadium.

Jones made his comments in a radio interview a day after coach Jason Garrett said, "I'm confident that the league will make sure that field is safe for everybody to play or we won't play the game."

Jones called the situation "interesting" in his radio interview and brought up a preseason game in Mexico City in 1994, when he said there were "clumps as big as softballs" in the Houston Oilers' 6-0 victory over the two-time defending Super Bowl champions.

"I can't believe when I look back on it that we kept playing in Mexico City," Jones said in the radio interview.

Jones later softened his remarks when he met with reporters, saying he has "such respect for what that organization is and what they are going to get done."

San Francisco coach Jim Tomsula moved some practices out of the stadium early in training camp after large chunks of sod came loose. There were similar issues when the stadium debuted last season. The turf was replaced after two Taylor Swift concerts on Aug. 14-15. Stadium operations chief Jim Mercurio has said it will be replaced as needed during the season, perhaps as many as six or seven times.

The year-old, $1.3 billion stadium is set to host the Super Bowl in less than six months. The NFL is expected to install its own field.

Cleveland QB situation

The Browns said their quarterback hierarchy hs not changed, even after Josh McCown injured a finger on his throwing hand during an 11-10 loss Thursday night to Buffalo. McCown threw interceptions on Cleveland's first two drives, raising questions about whether backup Johnny Manziel, who threw a touchdown pass and made a sensational play, was threatening to jump him on the depth chart.

But Browns coach Mike Pettine said Friday that Cleveland's depth chart at quarterback remains unchanged.

"We feel good about where Johnny is as the No. 2 and we feel good about where Josh is with the No. 1," Pettine said. "Our thoughts on the quarterback picture are the same this morning as they were going into last night."

McCown didn't duck criticism, calling his second game with the Browns "not the standard I want to play at."


•Pittsburgh Steelers rookie cornerback Senquez Golson underwent shoulder surgery and is out indefinitely. The second-round pick out of Mississippi has been on the physically unable to perform list since training camp began nearly four weeks ago.
