Tempers heated up more than once during practice Monday — which is curious, considering the entire session was climate-controlled.

A soggy South Florida morning forced the practice inside the team’s air-conditioned bubble, and perhaps the players were a little too close for comfort.

Jacquies Smith, a fourth-string defensive end, thought it wise to pick a fight with the left side of the Dolphins’ starting offensive line, sparking a small scuffle that was broken up with no significant harm done.

After a full-contact rep, Smith matched up with Richie Incognito, then began throwing haymakers at Incognito and Jake Long. Of course, they were all wearing pads and helmets, making it hard to do much damage.

“I have a lot of respect for those veteran guys, but in this league it’s kind of put up or shut up and you have to go out there and prove yourself a little bit,” Smith told Dolphins.com.

Both offensive and defensive lines briefly joined in the melee before cooler heads prevailed.

“We want to help each other out, but at the same time, if it’s O-line/D-line, you’ve got to go in there and do what you have to do for your line,” defensive end Jared Odrick said.

Said coach Joe Philbin: “I don’t know how it popped up, but inevitably at camp, especially now that [Monday] was the ninth heavy practice, you’re usually going to get into something.”

Notable

• Philbin appeared to get choked up when asked if he had reached out to Philadelphia Eagles coach Andy Reid in light of Sunday’s news that Reid’s son, Garrett, 29, had been found dead in a dorm room at Eagles training camp. Philbin, who lost a college-aged son last winter, declined to comment beyond a statement he released Sunday night.

• Wide receiver Clyde Gates (hamstring) was back in pads and appeared to practice without limitation after missing much of last week.

Backup offensive lineman Ray Feinga missed Monday’s practice with a minor ailment, but is expected back Tuesday, according to a league source.

• Quarterback Matt Moore got the majority of work with the first-team offense and had a good day. Two passes in particular stood out: His laser to Davone Bess on a deep slant, beating Richard Marshall, and a second completion tucked between two defensive backs.

•  Jeron Mastrud

Play of the day

Safety Reshad Jones had great coverage on Legedu Naanee’s out route, but Naanee made the catch anyway, a pretty snag on the sidelines.

Quotable

“I was thinking that [offensive linemen] were big, slow, dumb guys, but he seems to maybe break the mold from some of the other guys I’ve been around.” — Cameron Wake, on rookie tackle Jonathan Martin
