Some Tuesday afternoon quick hits:
### The arm issue that sidelined UM quarterback Jack Heaps from Monday’s scrimmage isn’t serious, according to Heaps.
Heaps, who had a pre-arranged interview with ESPN today but did not speak to the general media, told ESPN he is fine and looks forward to Wednesday’s practice.
UM has declined to say, to this point, whether he’s injured. But Heaps was wearing a protective sleeve over his right elbow during the scrimmage. And he was not rested Monday because the job has been settled.
The quarterback race had not been decided as of late Monday night. UM did not practice today.
A UM official said Brad Kaaya played OK during Monday’s scrimmage, very good at times, but also had some throws that weren’t especially sharp. Kaaya remains very much in the running for the job.
### From today’s Dolphins practice: Will Davis began the day as the No. 3 corner but Jamar Taylor finished the day in that job. Davis slipped and was beaten for a long touchdown by Kevin Cone….
Joe Philbin was non-committal about whether Knowshon Moreno would play in Saturday's preseason game against Dallas. During a break in practice today, Moreno ran over to the sideline to do conditioning work with Mike Pouncey....
Ryan Tannehill had several impressive deep throws: two to Damian Williams and one to Armon Binns.
John Potter, trying to replace injured Caleb Sturgis, hit three or four field goals. His 51-yarder hit the side of the goalpost. Sturgis declined to discuss his situation afterward....
Brady Quinn threw two interceptions and has three the past two days. He isn’t making a convincing case for the third QB job....
I asked Joe Philbin if Jordan Tripp, who got some more first team work today, appears able to make a contribution on defense and special teams this season or whether he’s a developmental prospect. Philbin said he likes what he sees and will know a lot more in the next two weeks.
"I thought he flashed some good things in the first couple of games," Philbin said. "He’s very smart, very hard working and diligent. I think it’s going to be an important two-week stretch for him to answer that question.”
The guards (Daryn Colledge on the left side and Shelley Smith on the right) remained the same as Monday...
Sam Brenner and Anthony Johnson returned to practice. Terence Fede, Jalil Brown, Sturgis and Marcus Thigpen remained out, and Daniel Thomas appeared limited. Walt Aikens left practice early, for good, with a finger injury....
Michael Egnew made a terrific catch on a sideline pattern from Matt Moore, the best catch I’ve ever seen him make.
### Agent David Falk tells us guard Toney Douglas, who finished last season with the Heat, has signed to play in China. Douglas wanted to return to the Heat, but Miami did not make an offer. Douglas appeared in 27 games for the Heat following his midseason acquisition and started 17 games, filling in when Dwyane Wade was injured... Free agent combo guard Leandro Barbosa is among several free agents being considered by the Heat.
### Heat single-game tickets go on sale on heat.com and ticketmaster.com at 10 a.m. Wednesday and at the AA box office at 10 a.m. Thursday.
### Jason Taylor, who left ESPN a year ago, took a job with NBC Sports Network on Tuesday, as an analyst on Pro Football Talk with Mike Florio.
