CLEVELAND, Ohio - The first day of Browns training camp is in the books, and the afternoon featured some big plays, some gaffes, a few injuries and a do-over at the end when coach Hue Jackson wasn't happy with a team drill.

Tyrod Taylor, working with the first team, made the play of the day when he fired a ball down the deep left side to Jarvis Landry. Baker Mayfield, working with the second team, connected with Rashard Higgins in 11-on-11s for a deep TD pass.

Linebackers Jamie Collins and Mychal Kendricks sat out team drills as they continue to recover from their surgeries, and fifth-round linebacker Genard Avery got some first-team reps at the Sam linebacker spot.

Greg Robinson, signed last month, worked behind Shon Coleman at left tackle. Second-round pick Austin Corbett worked with the second team at left guard. But Jackson said the club hasn't given up on the rookie yet at left tackle, even though Joe Thomas told NFL Network he's a guard.

The following players did not practice today due to injury: OL Desmond Harrison (toe-PUP), DB Jabrill Peppers (groin-NFI), DL Chad Thomas (hernia-PUP) and DL Trenton Thompson (illness-NFI).

The following players left the field with injuries today: TE Devon Cajuste (concussion), DL Caleb Brantley (cramps), DL Daniel Ekuale (calf), WR Damion Ratley (hip) and WR Derrick Willies (cramps).

Here's a look at some training camp highlights from day one.

1. Antonio Callaway blisters in 1-on-1

Callaway, the Browns' fourth-round receiver, tore up the defensive backs in 1-on-1 drills to the delight of the crowd. On one play, he beat Denzel Ward on a bomb from Mayfield.

Callaway sat out minicamp with a groin injury, but looked fast and healthy Thursday. In team drills, he dropped a sideline route from Mayfield, but if he keeps progressing, he could steal playing time away from Corey Coleman, who's filling in for Josh Gordon as the starting "X.''

2. Tyrod Taylor and Jarvis Landry connect

Taylor to Landry is becoming a familiar refrain, especially with Gordon absent. The three-time Pro Bowler caught passes all over the field, but made the play of the day on the long sideline reception. (Not shown in the tweet above). The Browns will count on these two to score a lot this season, and Landry is eager to improve on his 8.8-yard per catch average from a year ago.

3. Coleman getting his chance

Coleman is replacing Gordon until he returns, getting an early chance to impress. He's broken his right hand each of his first two years.

"Been hurt a lot, can't control that,'' he said. "That's really the main thing, haven't played a full season. It's tough when guys play half a season and come back, I start off great seasons, just too much starting over from the beginning, but I feel amazing right now."

Coleman made a few plays in practice, but will seek some big plays when the pads go on Saturday.

"He's competing,'' said Jackson. "He's here. He is accounted for and has been working hard. That is all you can do. All Corey can do is do his job. Do his job and what he is supposed to do, and the rest will take care of itself."

4. Myles Garrett starting strong

Garrett showed good burst after spending much of his offseason watching film of Julius Peppers. Garrett, with Emmanuel Ogbah healthy on the left side, is heeding defensive line coach Clyde Simmons' advice to not let himself get bullied.

On Saturday, when the pads go on, Mayfield will start to find out just how quick the game really is. On Thursday, in goal-line drills, he fired TD passes to tight end Davon Cajuste and Rashard Higgins from the 2. He also had the 60-yard TD to Higgins. It was a good first day.

Jackson saw the improvement.

"Normally, he would flush out to the right side when pressure came,'' he said. "He stood in there, especially in our scoring zone area, and made some plays. He stood there and threw the football. That was good to see, but we have to continue to do that.''

6. Taylor taking batting practice

Taylor's first rep of the 2018 camp was a goal-line pass batted at the line of scrimmage by Trevon Coley. But Taylor quickly recovered, caught the loose ball and ran it in. Taylor used his legs for a score on the next rep, then hit David Njoku in the end zone for a TD.

In later drills, he was picked off by second-year cornerback Denzel Rice. But Taylor is showing good command of the scheme, and scoring touchdowns.

"He does not flinch,'' said Jackson. "Tyrod Taylor is the same guy that walked into the building however many months ago and is the same guy today. He is leading the offense, making plays, getting people in the right spots and all of those things.

"I am very impressed with what he is doing. He just has to keep it going."
